- `imports`: Moves imports that have been moved or renamed in Apollo Client 4. Also moves types into namespace imports where applicable.
1818
- `links`: Moves `split`, `from`, `concat` and `empty` onto the `ApolloLink` namespace, changes funtion link invocations like `createHttpLink(...)` to their class equivalents like (`new HttpLink(...)`).
1919
Does not change `setContext((operation, prevContext) => {})` to `new ContextLink((prevContext, operation) => {})` - this requires manual intervention, as the order of callback arguments is flipped and this is not reliable codemoddable.
20+
- `removals`: Points all imports of values or types that have been removed in Apollo Client 4 to the `@apollo/client/removals` namespace. That export contains context for each removal, oftentimes with migration instructions.
